@Olivier5,
Quote:It is only logical that the upper floors -- located above the fires before the collapse -- would end up as debris located on top of the fires after the collapse.
That is not logical at all. Supposedly, in defiance of the laws of physics, this much smaller block of floors was what "pulverized" the much more massive in volume and build strength lower sections into dust.
Of course there were scientific theories, the pancake theory is one, that the news media dutifully trotted out to a highly gullible public. But the "scientific paper" that NIST finally settled on, the "scientific" paper that ultimately provided the entire fiction for NIST and the US official conspiracy theory, was one
first published on September 13, 2001!!!!!
That's pretty "scientific" isn't it, farmerman?
Conservation of momentum says not a chance. NIST did no study on this, they stopped at collapse initiation, because they knew full well that it was impossible according to long established Newtonian principles.
Why was NIST able to do a "full" study of WTC7 . Well, not actually a full study at all. Their silly computer simulation video of the collapse didn't match REALITY, the actual collapse of WTC7 recorded in many live videos.
That's also why NIST lied about no free fall for WTC7, then after it was pointed out, by a high school physics teacher, to all these marvelous "scientists", with the resources of the US government behind them, that free fall was an easily measurable thing, they changed their minds, but in a totally unscientific, highly deceptive fashion, in other words, the totally typical NIST fashion.
Watch these NIST scientists stumble and fumble around with what should have been easily described science when they were back in high school. The man who denied molten steel is especially telling. His body language and demeanor describe a man who is totally uncomfortable with his lies, not to mention his own stunning incompetence.
Watch it all but to see a really squirming John Gross, start at 5:42.
